Galvanized hlau
DX54D yog kub-dip coated sib sib zog nqus- kos hlau nyob rau hauv DX series, muaj nuj nqis rau siab formability. Ua los ntawm qis- carbon steel, nws zoo tagnrho rau kev sib sau txias. "DX" qhia cov koob, "54" qib formability, thiab "D" qhov tob- kos duab zoo. Ob leeg DX54D thiab DX53D yog cov tsheb hlau, tab sis DX54D muaj ntau dua formability, ua rau nws zoo dua rau cov duab complex. DX54D (sib npaug rau FeP06G, steel tooj 1.0952) yog siv nyob rau hauv automotive panels thiab cov khoom vaj tse, nrog corrosion kuj rau sab nraum zoov los yog ntub dej.

Kev kho deg ntawm DX54D Steel
Txhawm rau txhim kho corrosion kuj, hnav tsis kam thiab zoo li DX54D steel, peb muab ntau hom kev kho deg:
Passivation los yog Chromate Txheej: Applied post-galvanizing los tiv thaiv oxidation thiab txhim khu corrosion kuj.
Phosphating: Txhawb cov xim adhesion, feem ntau siv hauv tsheb thiab cov khoom tiav.
Organic los yog Epoxy txheej: Muab kev tiv thaiv ntxiv rau cov khoom uas raug hnav lossis ib puag ncig hnyav.
Qhov sib txawv nto tiav rau DX54D
DX54D + Z (zinc txheej): muab kev tiv thaiv corrosion zoo thiab tsim nyog rau kev siv sab nraum zoov thiab tsheb.
DX54D + ZM (zinc-magnesium alloy txheej): txhim khu kev tiv thaiv corrosion thiab txo cov xeb dawb, haum rau tsheb thiab cov khoom siv hauv cov chaw ntub dej.
DX54D+ZA (zinc{2}} txhuas alloy txheej): txhim kho qhov tawv tawv thiab corrosion kuj, haum rau cov tsev thiab facades.
DX54D+ZF (zinc- hlau alloy txheej): txhim khu xim adhesion thiab corrosion kuj, feem ntau siv rau tsheb qhov chaw uas yuav tsum tau pleev xim rau.
DX54D + AZ (txhuas-zinc alloy txheej): muab kev tiv thaiv corrosion siab thiab kev cuam tshuam ntawm tshav kub, dav siv hauv ru tsev, HVAC systems thiab cov khoom siv hauv tsev.
DX54D+AS (aluminium-silicon alloy txheej): txhim kho qhov kub thiab txias thiab tiv thaiv oxidation, haum rau lub tshuab tso pa thiab siab - qhov kub thiab txias.
Qhov Kev Kho Hniav Uas Muab Qhov Zoo Tshaj Plaws Corrosion Resistance rau DX54D Steel?
DX54D + AZ (aluminium-zinc alloy txheej) yog qhov kev xaiv zoo tshaj plaws rau cov ntawv thov uas yuav tsum tau muaj kev tiv thaiv corrosion tshwj xeeb, tshwj xeeb tshaj yog rau cov chaw raug xws li cov tsev thiab ru tsev.
